In current study, we demonstrated that GALNT2 and several other GalNAc-T subfamily members (GALNT3, GALNT4, GALNT10, GALNT13 and GALNT15) were associated with worse survival rate of cervical cancer patients, and GALNT2 also predicted unfavorable prognosis in HNSC, KIRC, LUAD, LUSC, STAD, READ and UCEC. The gene discussed is GALNT15; the disease is cervical cancer.
